👉 In mathematics, an undervaulted function is a function that has a discontinuity at every point. This means that there are infinitely many points where the value of the function changes from one side to another without any particular pattern or slope. For example, consider the function f(x) = x^3 - 2x^2 + 4x - 5. At x = 0, f(0) = 0 and at x = 1, f(1)
